Analysis Note

Protein homogeneity is evaluated by immunoelectrophoresis.

Application

Epithelial cells, mesenchymal cells, neuronal cells, fibroblasts, neural crest cells, endothelial cells

Fibronectin human foreskin fibroblasts has been used in extracellular matrix binding assay and probiglycan and cleavage assays. It has also been used in ectoderm (neuronal) differentiation and in the preparation of a semi-solid growth medium.

Biochem/physiol Actions

Fibronectin 1 (FN1) participates in cell adhesion, growth, migration, wound healing, blood coagulation and metastasis. Mutations in FN1 results in glomerulopathy. It plays an important role in cell attachment and spreading, control of cell cytoskeleton, morphology and differentiation. FN1 is also involved in extracellular matrix formation, hemostasis and thrombosis. Fibronectin production by normal human foreskin fibroblasts has been shown to improve two-fold after glucocorticoid treatment.

Caution

Vortexing, excessive agitation, repeated freezing and thawing of reconstituted fibronectin are not recommended.

General description

Fibronectin 1 (FN1) is a glycoprotein of the extracellular matrix that is coded by FN1 gene. It is expressed in the plasma and at the cell surface. It is mapped to human chromosome 2q35. Fibronectin is mostly synthesized by fibroblasts and endothelial cells.
